Ahh... good question!

So, a bunch of things here are documented in a spreadsheet that I only
got a copy of relatively recently.

That being said, I've found
src/usr/diag/prdf/common/plat/pegasus/Proc_acts_PB.rule
inside hostboot, which may end up being the ultimate documentation as
this is what HB is looking at?

grep xls src/usr/diag/prdf/common/plat/pegasus/Proc_acts_PB.rule
# p8dd1_mss_FFDC_73_final.xls
# p8dd1_mss_FFDC_73_final.xls
# p8dd1_mss_FFDC_73_final.xls
# based on p8dd1_mss_FFDC_59.xls
# based on p8dd1_mss_FFDC_37_ reviewd.xls
#Based on p8dd1_mss_FFDC_70.xls
# based on p8dd1_mss_FFDC_59.xls
#action updated based on p8dd1_mss_FFDC_59.xls
# FIR last updated based on p8dd1_mss_FFDC_37_ reviewd.xls
# RAS spreadsheet: p8dd1_mss_FFDC_37_ reviewd.xls
# RAS spreadsheet: p8dd1_mss_FFDC_72_ reviewd.xls on Jan 18,2014

So I guess that set of spreadsheets will end up explaining what's going
on? Or at least the design? Maybe combined with P8 workbook it ends up
making a cohesive picture of what's going on.
